Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains florasulam, be used to prevent and treat multiple weeds in field.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of valid approach, be that the agricultural chemicals of performance complement obtains best synergistic effect through the proportioning of adjusting different agricultural chemicals.

The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.Therefore, they kill careless ability and scope is also different.It is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
In recent years; People are frequent to be used and has concurrently to the safety of useful crop with to the so-called selective herbicide of the herbicidal effect of undesired plants; Even but have the weed killer herbicide of high selectivity; Because of various conditions such as the kind of meteorological condition, soil condition, crop, chemicals treatment periods, also produce poisoning sometimes in use.People are studying the use of the various poisoning palliatives of the such state of affairs of not expecting of reply.At present, China also comparatively payes attention to using with aspect the research of weed killer herbicide, is extensively thought one of important measures that weed killer herbicide rationally uses, and has worked out a series of Herbicidal compositions, has obtained bigger progress.
My company also is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers about the relevant composite product of florasulam with dicamba, Acetochlor, pendimethalin.

Below in conjunction with embodiment the present invention is further explained.
Practice example one:
Florasulam and sulfonylurea are mixed to the active determination test report of wheat paddock weeds
Test objective: under the greenhouse pot culture condition, measured florasulam and sulfonylurea and different blended combo thereof and closed herbicidal effect to clearvers; And estimate its synergy, for the formulation development and the agriculture chemical registration field control effectiveness test of Mixed Pharmacy provides scientific basis.
Supply the examination target: clearvers (Rubiaceae Galium).
Test medicine: florasulam (florasulam) 97% former medicine, dicamba (dicamba) 98% former medicine, Acetochlor (acetochlor) 93% former medicine, pendimethalin (pendimethalin) 95% former medicine, agricultural chemicals Co., Ltd of U.S. nation provides by Shaanxi.
The medicament configuration:

Test method: adopt potted plant cauline leaf facture (NY/T 1155.4-2006): the amount of setting soil in the polypots of high 6cm, diameter 9cm; To supply 15～20 sowings of examination target weed seed in polypots; Be placed on cultivation in the greenhouse after covering the thick fine earth of 0.5～1cm, treat that weeds grew to for 1～3 leaf phase and carry out cauline leaf spraying processing, every alms bowl spraying liquid 1mL; Every processing repetition 4 times, and establish the contrast that is treated to that does not contain medicament.Handle back examination material and place in the greenhouse in and cultivate, the growing state of routine observation target weeds, be injured symptom and growth inhibition situation of range estimation target behind the 15d, and claim acrial part fresh weight or strain fresh weight, with the toxicity action of form fresh weight inhibiting rate evaluation medicament to the target weeds.
Investigation method:
Range estimation target be injured symptom and growth inhibition situation are handled behind the 15d in test, and claim to calculate fresh weight inhibiting rate (%) by the acrial part fresh weight.
The synergy evaluation method:
Estimate weed killer herbicide synergy mode (NY/T 1155.7-2006) according to the Gowing method, its formula is following:
E
0＝X+Y-XY/100
In the formula, X is that florasulam is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is that sulfonylurea is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for a kind of two kinds of pharmacy mix in florasulam and the sulfonylurea to the theoretical value of target weeds fresh weight inhibiting rate; When E is a kind of two kinds of pharmacy mix in florasulam and the sulfonylurea to the measured value of target weeds fresh weight inhibiting rate.
Evaluation criterion: work as E-E
0Be expressed as synergistic effect at＞10% o'clock, as-10%≤E-E
0Be expressed as summation action, and worked as E-E in≤10% o'clock
0Be expressed as antagonism at＜-10% o'clock.
